I have a newly installed domain controller for a client of mine that
I'm having a problem with, and am hoping I can get some good advice
on
tracking down the problem. This is for a small office, with about 8
computers total. This server is the first domain controller, as
previously the network was set up with all stand-alone computers.
It's
a custom built box running Windows 2003 Small Business Server SP2.
Hardware specs are AMD Athlon 64 X2 Dual Core 3800+ with 2GB RAM.

The problem I'm trying to solve is Event ID 1054 appearing in the
Application Log every 5 minutes like clockwork, for the last few
months now.

I'm thinking this is a TCP/IP or DNS issue, and I'll explain why. I
thought I had the problem solved recently, after noticing some
invalid
entries in the DNS server. I saw entries pointing to the server's
hostname, with an IP address of 169.254.x.x, which reminded me of
many
forum posts and articles in the past referring to problems you can
have on a domain controller with multiple NICs, and this server does
have 2 NICs. One I had configured with a valid static IP address, and
the other was enabled, but not connected to the network and no IP
address assigned. I think that this second network card was causing
the 169.254 entries to appear in DNS. So, I disabled the 2nd NIC, and
cleaned up all the bad entries in DNS. I thought I had fixed it!
There
were no further errors for 4 hours, but during the night, they
started
again. It was strange though, because the first night, they were only
happening every 15-30 minutes, instead of the standard 5 minutes that
it has been happening with for the last few months. But, even now,
it's back up to every single 5 minutes, I get a new entry in the
event
log.

Can anyone offer any advice as to further troubleshooting steps I
should take with this server? I really don't want to scrub the hard
drives and start over, but I'm afraid that might be my only choice at
this point! Thanks much in advance!!!!

I am continously getting this warning message in the DNS event log after we
installed SP2 to our windows 2003 Root AD Server. I saw some of the post here
people also received 9002 event error. but in my case I don't see any.

I have restarted net logon service , this does since to fix the problem. any
help or suggestion will be really appreciated.
